Help!: Help adding event

I have added a run (20km de Paris):

http://www.mapmyrun.com/event/france/paris/439453764

After entering this event, I noted that the date (Oct 14, 2007) is not showing on the site and I am unfortunately unable to edit the information since I allways get an error at step 2 of the editing process. Could you please fix this

Thanks

PS I am not part of the organisation of this event but I will sure participate!
